??? Error using ==> evalfismex Illegal parameters in fisGaussianMF() --> sigma = 0
Error in ==> evalfis at 84 [output,IRR,ORR,ARR] = evalfismex(input, fis, numofpoints);
Error in ==> myfuzz1 at 28 z(i,j)=evalfis([p1 p2 p3 p4 p5 p6 p7 p8 p9],t);
can anybody tell what is the meaning of this error and how can i solve it

My guess is that you somehow defined a Gaussian membership function with sigma set to 0. Here is the doc page explaining what Gaussian membership function is and what sigma is.
HTH.
